Thing Explainer

The world is complex. Thing Explainer: Complicated Stuff in Simple Words aims to make understanding it a little easier. Penned by Randall Monroe, creator of the webcomic xkcd, this humorous look at the world covers topics ranging from the little bags of water you're made of (cells) to the stuff you use to steer a plane (airliner cockpit controls), each explained using detailed diagrams, but only the thousand most common English words. So no matter your reading level, you should be able to explain the space car for the red world (Mars Curiosity Rover) to anyone who asks.
